Kernel for Galaxy S24, rebased on CLO sources (WIP)
0649dc0af9
commit 92382d744176f230101d54f5c017bccd62770f01 upstream.
A recent change in clang allows it to consider more expressions as
compile time constants, which causes it to point out an implicit
conversion in the scanf tests:
lib/test_scanf.c:661:2: warning: implicit conversion from 'int' to 'unsigned char' changes value from -168 to 88 [-Wconstant-conversion]
661 | test_number_prefix(unsigned char, "0xA7", "%2hhx%hhx", 0, 0xa7, 2, check_uchar);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/test_scanf.c:609:29: note: expanded from macro 'test_number_prefix'
609 | T result[2] = {~expect[0], ~expect[1]}; \
| ~ ^~~~~~~~~~
1 warning generated.
The result of the bitwise negation is the type of the operand after
going through the integer promotion rules, so this truncation is
expected but harmless, as the initial values in the result array get
overwritten by _test() anyways. Add an explicit cast to the expected
type in test_number_prefix() to silence the warning. There is no
functional change, as all the tests still pass with GCC 13.1.0 and clang
18.0.0.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
